Apart from releasing the public build of iOS 14.1 and iPadOS 14.1, Apple has also seeded the fourth beta of iOS 14.2 to developers.
The first beta of iOS 14.2 added some nice new features including deeper Shazam integration, a beautiful Music widget for the Control Center, and more. The second and third beta builds only fixed some bugs and did not introduce any other changes. It is unlikely that the fourth beta changes this as Apple is now likely focusing on fixing the bugs and stability issues ahead of the public release of the next month.
Apple will presumably release iOS 14.2 to the public ahead of the launch of the iPhone 12 mini and the iPhone 12 Pro Max next month.
